Unable to start a ktor server with this error.
Exception in thread "main" io.ktor.server.engine.internal.ReloadingException: Module function cannot be found for the fully qualified name 'com.blackfox.myoutfitpicker.ApplicationKt.module'
at io.ktor.server.engine.internal.CallableUtilsKt.executeModuleFunction(CallableUtils.kt:27)

I am following the instructions at
https://ktor.io/docs/eap/creating-http-apis.html#order_routes

import io.ktor.server.application.*
import com.blackfox.myoutfitpicker.plugins.configureRouting
import com.blackfox.myoutfitpicker.plugins.configureSerialization

fun main(args: Array<String>): Unit = io.ktor.server.netty.EngineMain.main(args)

fun Application.module() {
    configureRouting()
    configureSerialization()
}

I have no idea what I am doing wrong.

What's in your application.conf ? Might be the package-name there is different so it can't find the specified module perhaps?

[Aleksei Tirman [JB]]

And check that a source file with the Application.module definition is named Application.kt .

@Steffen Lien and @Aleksei Tirman [JB]

ktor {
    deployment {
        port = 8080
        port = ${?PORT}
    }
    application {
        modules = [ com.blackfox.myoutfitpicker.ApplicationKt.module ]
    }
}

And the application source, which you can also see at https://github.com/jblack975/MyOutfitPicker

package com.blackfox.myoutfitpicker

import io.ktor.server.application.*
import com.blackfox.myoutfitpicker.plugins.configureRouting
import com.blackfox.myoutfitpicker.plugins.configureSerialization

fun main(args: Array<String>): Unit = io.ktor.server.netty.EngineMain.main(args)

fun Application.module() {
    configureRouting()
    configureSerialization()
}

@James Black Either change the filename Main.kt to Application.kt or change the modules part in your application.conf to modules = [ com.blackfox.myoutfitpicker.MainKt.module ] . The <File>Kt part of the modules is looking for a specific file called exactly that as I recall (haven't tried to run your project)

[James Black]

Thanks @Steffen Lien. I didn't realize the filename was the important part here. It runs now.
